Abstract

Seven species of chirostyloidean squat lobsters are reported from the Galapagos Rift zone and Galapagos platform: Eumunida subsolanus n. sp. (Eumunididae), Heteroptychus galapagos n. sp., H. nautilus n. sp. (Chirostylidae), Uroptychus bellus Faxon, 1893, U. compressus n. sp., U. occidentalis Faxon, 1893 (Chirostylidae), and Sternostylus defensus (Benedict, 1902) (Sternostylidae). All new species are described and illustrated, and the two species previously known from the Galapagos Islands, Uroptychus bellus and U. occidentalis, are re-illustrated from respective lectotypes, herein designated, since both original descriptions were only brief. Both the species of Heteroptychus and Eumunida subsolanus are the first representatives of their respective genera in the eastern Pacific and the latter is also the first record for the family Eumunididae in the region.
